安装步骤

本文是spark2.4.0基于scala2.10.6的spark安装！
spark下载链接：http://mirrors.shu.edu.cn/apache/
scala下载链接：https://www.scala-lang.org/download/2.10.6.html

scala解压复制到所有节点

[[email protected] ~]$ tar -zxvf scala-2.10.6.tgz
[[email protected] ~]$ scp -r /home/hadoop/scala-2.10.6/ slave01:/home/hadoop/
[[email protected] ~]$ scp -r /home/hadoop/scala-2.10.6/ slave02:/home/hadoop/

spark解压

[[email protected] ~]$ tar -zxvf spark-2.4.0-bin-hadoop2.6.tgz

更改spark名字（个人习惯）

[[email protected] ~]$ mv spark-2.4.0-bin-hadoop2.6 spark-2.4.0

配置环境变量

[[email protected] ~]$ vi .bash_profile
PATH=$PATH:$HOME/bin
export HADOOP_HOME=/home/hadoop/hadoop-3.2.0
export HIVE_HOME=/home/hadoop/hive-3.1.1
export SPARK_HOME=/home/hadoop/spark-2.4.0
export SCALA_HOME=/home/hadoop/scala-2.10.6
export PATH=$PATH:$HADOOP_HOME/bin:$HADOOP_HOME/sbin:$HIVE_HOME/bin:$SPARK_HOME/bin:$SCALA_HOME/bin

使环境变量生效

[[email protected] ~]$ source .bash_profile

spark-env.sh文件配置

[[email protected] ~]$ cd spark-2.4.0/conf/
[[email protected] conf]$ cp spark-env.sh.template spark-env.sh
[[email protected] conf]$ vi spark-env.sh
export JAVA_HOME=/usr/java/jdk1.8.0_201-amd64 #Java环境变量
export SCALA_HOME=/home/hadoop/scala-2.10.6 #SCALA环境变量
export SPARK_MASTER_IP=master #驱动器节点IP
export SPARK_WORKING_MEMORY=1g #每一个worker节点上可用的最大内存
export HADOOP_HOME=/home/hadoop/hadoop-3.2.0 #Hadoop路径
export HADOOP_CONF_DIR=$HADOOP_HOME/etc/hadoop #Hadoop配置目录

slaves文件配置

[[email protected] conf]$ vi slave
slave01
slave02

spark目录文件同步到其他节点

[[email protected] ~]$ scp -r /home/hadoop/spark-2.4.0/ slave01:/home/hadoop/
[[email protected] ~]$ scp -r /home/hadoop/spark-2.4.0/ slave02:/home/hadoop/

启动spark

进入sbin目录启动spark

[[email protected] ~]$ cd spark-2.4.0/sbin/
[[email protected] sbin]$ ./start-all.sh

验证spark是否成功

jps命令查看

[[email protected] sbin]$ jps

39362 Master # spark主进程
33829 NameNode
34278 ResourceManager
34055 SecondaryNameNode
38828 QuorumPeerMain
39423 Jps

[[email protected] ~]$ jps

29880 Worker # spark工作节点进程
28489 DataNode
